BUNDY HILL prefixes in area code 517

NANPA records 3 assigned NXX blocks to rate center BUNDY HILL in area code 517, 0.5% of the 616 blocks assigned in the code. A rate center is the billing geography a block is allocated to – NANPA truncates the name to ten characters, so read it as a NANPA label rather than a town. 3 holders hold those blocks, the largest being BANDWIDTH.COM CLEC, LLC - MI (1), FRONTIER COMMUNICATIONS OF MICHIGAN, INC. (1), ACD TELECOM, INC. - MI (1). The earliest assignment on record here is 2002-06-18 and the most recent 2024-08-20. 2 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
